Application of Natural Surfactants for Enhanced Oil
Mar 01 2019 · Utilization of different types of surfactants (synthetic or natural) in order to decrease the water-oil interfacial tension (IFT) is one of the most common methods for EOR. However polymers and synthetic chemicals have a number of disadvantages such as linking to fossil fuels high cost and environmental impacts.

Part of the chemical acts like water and part acts like oil. By definition a surfactant is a long-chain organic molecule that has a polar (water-like) and a non-polar (oil-like) end. Emulsifiers also have water- and oil-like ends but are used to aid in the temporary mixing of oil and water to form an emulsion.
